Back to the drawing board

Well not all the way back. The panels I was going to get are now sold out.
It was to have been 3- 210w 33.2voc 7.9imp panels in series to an mppt controller and then to 4- 6v 225 amp hour batteries. (polycrystaline cells)

Now I have found 4-175 watt 44.2voc 4.95imp (mono crystaline cells) same charge controller (outback flexmax 60 mppt) same 4 batteries but two sets of two panels in series and then the two sets paralleled.

How does that sound in comparison?

What size wire would be best for a 25 foot run between panels and charge controller?
